On the basis of the insolation received by the surface of the Earth, the world is divided into three main heat zones. They are:

 

 

Torrid Zone: This zone lies between to 23 1/2 0 North to 23 1/2 0 South to the Equator. The Sun shines exactly overhead at the places near the Equator and in the tropics. Direct vertical rays of the Sun fall over these places. Therefore, equatorial and tropical regions receive maximum insolation.

 

 

Temperate Zone: This zone lies between 23 1/2 0 to 66 1/2 0  North and South of the Equator. The regions in the temperate zone experience the slanting rays of the Sun. Due to the spherical shape of the Earth, the amount of insolation received by these regions is less.

 

 

The Frigid Zone: This zone is located between 66 1/2 0 and 900North and South of the Equator. This zone experiences extremely slanting rays of the Sun over a large distance. Hence the amount of insolation received is much less.
